Research on Ceramic Sanitary Ware Defect Detection Method Based on Improved VGG Network

Le résumé fourni par la source

Abstract The defect detection of ceramic sanitary ware is often done manually, which is inefficient and unhealthy. The development of deep learning technology makes a non-contact and high-efficient method of inspection possible. In this paper, based on VGG-16 network, we proposed an optimized method for ceramic sanitary ware defect detection. We carried out pre-processing to denoise and enhance the original image data, improved activation function of MReLU, and used transfer learning method to train the model. The results of the test on the ceramic sanitary ware defection data set showed that the accuracy can reach 97.48%, which is 6.46% higher than that of the model using the ReLU activation function. The detection speed can reach 7 fps, which could meet the requirements of industrial online real-time production.
